Hi,
I'm trying to find out what size load bearing steel beam, and supporting pillars, should be used when building a 8x8m open living room.
The house is a one storey "modern" (shed roof) house with 20x20cm pillars and 20x20x60 Q-Con blocks for outer walls, and 7.5cm Q-con for inner walls.
Anyone here who knows?
Cheers,
Val
